I finally got the 8.8 english software to download, had to use a VPN mapped to Japan...anyways, now that its downloaded, i see no option to change themes, the app is very bare. In the downloaded files, theres no "usb" "monitorL" thing like it says in the instructions. Also, its an absolute struggle to get my pc to recognize the USB. The screen powers on, but my PC is not liking the USB for some reason? I need help please
